SHAFT-HANGER.

SPECIFICATION forming part of Letters Patent No. 319,00 dated June 2, 1885.

Applicatizn filed January 24, 1895. x model.)

If 0 all whom it may concern:

Be it known that I, PHILIP Mnnxnr, a citi zen of the United States, and a resident of St. Louis, in the State of Missouri, have invented a new and useful Improvement in Shaft-Hangers; and I do hereby declare the following to be a full and accurate description of the same, reference being had to the annexed drawings and letters of reference marked thereon, as a part of this specification.

My invention relates to shaft-hangers; and the object of it is to provide the trade and consumer with an adjustable shafthanger which is simple in its operation, cheap and durable in its construction, and one upon which the shaft-box can be readily and easily adjusted to suit the position of the shaft.

It consists, first, in providing the arms of the hanger with lateral slots adapted to hold screw-bolts in such a manner that they may be readily shifted from side to side, so as to thus shift the box which they support from one side to the other.

It consists, second, in having two screwbolts, each made with threads at each end and nuts to fit them, said screw-bolts being thus adapted to move up and down in the slots of the arms and hold the shaftbox so that said shaft-box may be moved up and down by screwing the nuts up or down to suit the elevation of the shaft to be hung.

It consists, third, in having one of these screw-bolts provided with a square or elongated loose head made to fit into an elongated hole in the shaft-box at the top of the upper lobe of the shaft-box adapted to allow a slight oscillation of the box while the shaft is being hung or in motion, thus preventing the bind ing, which would occur in a box held rigidly by the screw-bolts, when the shaft is slightly bent, and allowing the box to be easily adjusted to suit the line of the shaft when the hanger has not been put up exactly perpendicular to the line of the shaft.

Figure 1 in the drawings is a front elevation view of my hanger with the box attached, the upper part of said box being partly cut away, showing a cross-section of the elongated hole and the elongated or square head of the screw-bolt, and the lower arm of the hanger being shown in section or cut away, so as to show the whole length of the screw-bolt in posit-ion. Fig. 2 is a side elevation of my hanger with the box attached and in place, with the lower arm of the hanger cut away, showing the lateral slot in the arm, the lower screw-bolt in position, and an end view of the shaft-box. Fig. 3 is a top view of the hanger without the box attached, showing the lateral slot in the arm, a cross-section of the screwbolt in a line with the top of the arm.

A is a shaft-hanger with two arms and a base to fasten it to the post or timber. It is provided with a lateral oblong slot at the end of each arm. Said slots are designated by letters S S. These slots are made with their greater lengths running with the arms and passing clear through the arms from top to the bottom, so as to admit of the screw-bolts being shifted from one side to the other to suit the position of the box.

B is an ordinary shaft-box made with an oblong hole or recess, It, at the top of the box B to receive and contain the loose head 0 on the end of the screw-boltf.

f and f are two screw-bolts, each made square or oblong at their centers to prevent them from turning in their oblong lateral slots 3 8. They are each provided with threads on each end out down on the bolt sufficiently far on the bolts to enable them to be moved up and in the arms of the hanger A by their nuts N N. The scrcwbolt f is provided at its upper end with a round end, which enters a round hole of equal size on the under side of the box B, and serves to hold the lower part of the boxB in position. The screw-bolt f is made like f, and has a round end at the bottom which enters a square or oblong piece of metal, 0, which piece of metal is made to fit loosely in the oblong recess R in its longer diameter, and thus operates to allow the box to oscillate up and down at its ends, but made to fit tightly in the oblong recess It in its shorter diameter, thus operating to prevent the body of the box from moving to or from the hanger A. Of course the recess R has its longer diameter running with the line of the shaft which the box is intended to support.

It will readily be observed from the above description that the box B can be easily adjusted to suit the required position of the box,

ICO

. shifted to the left, the screw-bolts can be shifted to the left in the slots 8 s; and if thebox is to be lowered orelevated to suit the position of the shaft the screw-boltsff can be screwed upor down;and if the line of the screw-bolts ff or the hanger A does not happen to be hung perpendicular to the line of the shaft in the box B, then the longer diameter of the re cess R in the top of the box will take up the Variation that the hanger will assume from the perpendicular, and thus avoids the necessity of attaching the hanger in an absolutely perpendicular position. Thus my hanger, being constructed as above described, enables the person using it to readily and completely adjust the box to suit the position of the shaft which it supports. The recess R also permits the box to oscillate with the movement of the shaft when the shaft is in motion, so that when the shaft happens to be bent at or nrar the box it prevents the friction which would otherwise occur.

Now, what I claim, and for which i ask Letters Patent to be granted me, is

1. In a shaft-hanger, the lateral slots 8 s in the arms of the hanger adapted to receive and i hold the screw-bolts f f and permit them to be shifted from side to side, for the purposes set forth.

2. In a shaft-hanger, a loose head, 0, on the screw-bolt f, fitting the recess R tightly in its shorter-diameter and loosely in its longer diameter, all operating to take up any variation which the shaft-hanger A, when put up, may

have from a perpendicular to the line of the PHILIP MEDARTJ Attestz WM. M. ECOLES, A. A. PAXSON.
